Daniel Weber M.Sc. Ph.D.


Daniel Weber began his study of Oriental Medicine in 1969 in Boston. He studied with J. R. Worsley and J. D. van Buren in the UK from 1974 before receiving his B.Ac. Daniel went to Japan in 1976 and studied with Dr. Masahiro Oki and Dr. Okada. He has been in practice in Sydney Australia since 1977 and created the first English language data base for Chinese herbal medicine in 1992. This data base was awarded 'Innovations in Australian Design' and put on exhibit in the Powerhouse Museum.

Daniel has studied in China from 1988, visiting more than a dozen times with numerous awards and two honorary Ph.Ds as well as being an advisor to Hangzhou TCM Institute in Hangzhou. Daniel has a Master of Health Science (Aust) and is completing his research Doctorate. Daniel is not just an academic but a committed clinician, and continues a clinic as well as his ongoing studies. His research into complimentary cancer treatments and his seminars to practitioners in Australia, South Africa and the US have attracted positive comment from leaders in the field. He is committed to creating a dialogue between all types of health care professionals.

Context Colorectal neoplasm and coronary artery disease (CAD) share similar risk factors, and their co-occurrence may be associated.


Objectives To investigate the prevalence of colorectal neoplasm in patients with CAD in a cross-sectional study and to identify the predisposing factors for the association of the 2 diseases.


Design, Setting, and Participants Patients in Hong Kong , China , were recruited for screening colonoscopy after undergoing coronary angiography for suspected CAD during November 2004 to June 2006. Presence of CAD (n = 206) was defined as at least 50% diameter stenosis in any 1 of the major coronary arteries; otherwise, patients were considered CAD-negative (n = 208). An age- and sex-matched control group was recruited from the general population (n = 207). Patients were excluded for use of aspirin or statins, personal history of colonic disease, or colonoscopy in the past 10 years.


Main Outcome Measures The prevalence of colorectal neoplasm in CAD-positive, CAD-negative, and general population participants was determined. Bivariate logistic regression was performed to study the association between colorectal neoplasm and CAD and to identify risk factors for the association of the 2 diseases after adjusting for age and sex.


Results The prevalence of colorectal neoplasm in the CAD-positive, CAD-negative, and general population groups was 34.0%, 18.8%, and 20.8% (P < .001 by ?2 test), prevalence of advanced lesions was 18.4%, 8.7%, and 5.8% (P < .001), and prevalence of cancer was 4.4%, 0.5%, and 1.4% (P = .02), respectively. Fifty percent of the cancers in CAD-positive participants were early stage. After adjusting for age and sex, an association still existed between colorectal neoplasm and presence of CAD (odds ratio [OR], 1.88; 95% confidence interval [CI], 1.25-2.70; P = .002) and between advanced lesions and presence of CAD (OR, 2.51; 95% CI, 1.43-4.35; P = .001). The metabolic syndrome (OR, 5.99; 95% CI, 1.43-27.94; P = .02) and history of smoking (OR, 4.74; 95% CI, 1.38-18.92; P = .02) were independent factors for the association of advanced colonic lesions and CAD.


Conclusions In this study population undergoing coronary angiography, the prevalence of colorectal neoplasm was greater in patients with CAD. The association between the presence of advanced colonic lesions and CAD was stronger in persons with the metabolic syndrome and a history of smoking.
